Elevator Emergency Procedures Flashcards
3 principles causes for failure of an elevator
- Electrical power failure
- Failure of the control circuit

Emergency door release devices

If the building has two elevators and one hoistway, emergency door release devices and keys should be found on the ground floor level and also at the top floor level
